Research Abstract

In order to identify molecules involved in lymphocyte recirculation, particularly interactions between lymphocytes and HE (high endothelial) cells, we tried successfully to establish cultured cell lines derived from rat high endothelial venules (HEV). We then developed an in vitro assay with which to quantitate lymphocyte interaction with HE cells, a most important process in lymphocyte recirculation. We have made number of attempts to generate monoclonal antibodies (MAb) which can block this heterocellular interaction, and have subsequently obtained two MAb, one of which recognizes the rat ICAM-1, the other the rat LFA-1. By the use of the in vitro assay described above, we investigated the extent of contribution of the LFA-1 and ICAM-1 molecules in lymphocyte-HEV interaction. We have demonstrated that; (1) neither LFA-1 nor ICAM-1 plays a significant role in interaction between resting lymphocytes and HEV, (2) when lymphocytes are activated, LFA-1 dependent adhesion pathways becomes operative, although, depending on the extent of activation, ICAM- 1 dependent adhesion pathway is differentially used in the interaction between lymphocytes and HE cells. Further attempts are being made to identify molecules directly involved in lymphocyte-HE cell interaction.
